| n | B’s view
(responder): |
||||||||||||
| n | Message 1 b getss from ‘a’:
a.na |
||||||||||||
| n | Message 2 b sends to j:
b.{a.na.nb}ServerKey(b) |
||||||||||||
| n | Message 4 b gets from ‘a’:
{a. kab}ServerKey(b)
.{nb}kab |
||||||||||||
| n | In CSP
this behavior can be modeled as follows: |
||||||||||||
| Responder(b,nb ) = |
|||||||||||||
| [] (receive.a.b.a.na g send.b.J.b .{a.na.nb}ServerKey(b) |
|||||||||||||
| kab
e Key g receive.a.b.{a. kab}ServerKey(b)
.{nb}kab |
|||||||||||||
| nb e Nonce g Session(b,a,kab,na,nb)
) |
|||||||||||||
| m e T |
|||||||||||||
